AENOR N Mark for PVC-U sections for doors and windows

​The AENOR N Mark covers unplasticized polyvinyl chloride (PVC-U) sections for the manufacture of doors and windows with laminated or lacquered sheets in accordance with Standard UNE-EN 12608

As a compliance assessor, AENOR is a leading product certification entity. The N Mark has been used to certify more than 100,000 products in more than 40 countries and is one of the world's five most widely used product quality marks.

The AENOR N Mark is a voluntary marking that allows a company to demonstrate that its product complies with specific provisions compiled in a UNE, EN or ISO standard or in a technical specification. This demonstration of compliance during the manufacturing and testing of the final products, based on a rigorous control performed by AENOR, will allow licensees of the Mark to put their products on the market with a high standard of quality, instilling confidence in the users of these certified products.

This way, the AENOR N Mark can provide the following advantages:

APPLICATION

The AENOR Mark is voluntary. Companies that want AENOR to certify their product must submit their application in accordance with the formats established by AENOR. This application must include information about the company and the characteristics of the products for which certification is sought.

Once AENOR technical staff have analysed the documents, compliance assessment activities will be performed in order to verify that the products comply with the applicable standards:

AUDIT/INSPECTION

A visit is made to the production centre to carry out the following procedures:

• a) the quality management system is audited in accordance with the UNE-EN ISO 9001 requirements that are directly related to the production process.
  
• b) The manufacturer's manufacturing process and production controls are inspected to ensure the product complies with the requirements of the standard.
  
• c) Samples are taken and sent to an accredited laboratory, which performs the tests included in the standards. The manufacturer sends samples identified by the auditor to the laboratory.
  

TESTING

The laboratory performs the tests established by the standard and sends its report to AENOR.

GRANTING​

Using all the information on the activities performed, the Technical Certification Committee (independent body comprising all the interested parties: manufacturers, the Administration, users, monitoring entities and AENOR) will either propose to AENOR that the Mark be granted, or request that one of the activities be repeated due to non-compliance.

Once the Certificate has been granted, the process will continue as the monitoring activities required to keep it must be performed. Samples will be taken, and audits, inspections and tests will be performed on an annual basis. The result is assessed every year by the Plastics Technical Certification Committee, which decides whether or not to uphold the Mark

Once the organisation passes the certification process, it obtains: ​

• The AENOR product certificate
  
• A licence to use AENOR's Mark of certified products
